Not replacement, had a bunch of bone grinding done, ball socet was wore and was pincing of blood flow and nerves going to my hand, I couldn't zip up right handed for a year before sergury, or raise my elbow past my nipple, after surgery, 55 minutes of that I had my elbow taped to misidentified for 3 days, therapy for 3 months two days a week, then one day a week for another two months, it fixed everything. And this has been 19 years ago.
